Zoning and Humidification
1 A DEDICATED TRANSFORMER SHOULD POWER THE HZ432. IF A DIFFERENT TRANSFORMER IS USED TO POWER THE EIM,
THE JUMPER FROM R TO RH NEEDS TO BE REMOVED AND THE RH AND RC FROM EIM GETS WIRED TO R ON THE ZONE
THAT THE EIM IS WIRED TO.
THE VISIONPRO THERMOSTAT CAN BE POWERED FROM ANY TRANSFORMER. IN THIS EXAMPLE IT IS WIRED BACK TO THE EIM.
2
3 DOTTED LINES ONLY APPLY TO MULTI-STAGE EQUIPMENT. SEE HZ432 INSTALLATION INSTRUCTIONS FOR HEAT PUMP WIRING.
RH/RC JUMPER INSTALLED WHEN SINGLE HEAT/COOL TRANSFORMER IS USED.
4
5 TO SIMPLIFY THE DIAGRAM, THE VISIONPRO IS CONTROLLING ZONE 4 BECAUSE IT IS LOCATED ON THE SAME SIDE OF THE
EQUIPMENT WIRING ON THE PANEL. THE VISIONPRO COULD BE WIRED TO ANY ZONE ON THE HZ432 AND IS MOST
COMMONLY WIRED TO ZONE 1.
Fig. 348. RedLINK VisionPRO thermostat controlling one zone with an HZ432 zone panel and a TrueSTEAM humidifier.
Setting up Humidification Control on RedLINK VisionPRO Thermostats
Select the terminals wired to the humidifier at ISU 803 (U1, U2, U3). In Fig. 348, the humidifier is wired to U1. To humidify in all
zones, set ISU 807 Humidifier Control to "Hum Controls Fan." Call Honeywell zoning at 1-800-828-8367 if you need assistance with
the zoning controls.
